Pocahontas never had a relationship with John Smith
She is a mature lady who falls in love with John Smith in the Disney adaptation of Pocahontas. This couldn't be further from the truth in reality. John Smith first encountered the Powhatan tribe when he was 27 years old, and Pocahontas was between the ages of 9 and 11. Additionally, he terrified the communities by breaking into people's homes at night and demanding supplies while holding guns to their heads. After being detained, John Smith was finally taken into custody for attempted murder. It only makes sense that Smith chose to depict himself as the protagonist of the tale as opposed to a thief who was attempting to take from helpless victims.
When the Spanish started attacking the Powhatan tribe, Pocahontas' father finally consented to collaborate with John Smith. Spain was a shared adversary, thus they were able to cooperate to ward them off. They started coexisting peacefully after Chief Wahunsenaca proclaimed John Smith to be the leader of the white men.
Young Pocahontas was described by John Smith as bringing food to the settlers and playing with English settlers' kids. But this might also be a falsehood. She was 12 miles from Jamestown, and a big river separated the two. She would have had to go against her father's wishes, go back and forth perhaps for days, and carry a canoe over the river.
